What to do

High tree pollen risk today. You may feel it before the day looks obviously bad.

  • Take your usual hay fever precautions before heading out.
  • Sunglasses and a quick clothes change after being outside may help.
  • Wind is likely to move pollen around more than usual, so symptoms can show up away from obvious green spaces.
  • Rain should help wash some pollen out of the air, although levels can still rise again when it dries out.
Antihistamine?Consider your usual antihistamine early.
